The JBX43785 70-meter LC/UPC to ST/APC simplex fiber patch cable represents professional-grade connectivity for modern optical networks. This single-strand singlemode fiber cable is engineered to meet the rigorous demands of telecommunications infrastructure, data centers, and enterprise network installations. **Technical Excellence:** Utilizing 9/125 singlemode fiber with G.657.A1 specifications, this cable delivers exceptional performance characteristics. The LC/UPC termination provides superior return loss performance (≥20dB), while the ST/APC connector ensures reliable mating. With insertion loss of only 0.15dB typical at standard wavelengths, signal degradation remains minimal even across the full 70-meter run. **Build Quality & Compliance:** The yellow riser-rated (OFNR) PVC jacket provides fire safety compliance and durability in plenum and non-plenum environments. The 1.8mm outside diameter enables efficient cable management through existing conduit infrastructure. Manufactured in Taiwan, US, or China with consistent quality standards, each cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A-2001. **Regulatory Compliance:** Fully TAA compliant and RoHS/ELV certified per EU Directive 2002/95/EC, making it suitable for government and enterprise procurement. The plastic accessory housing ensures corrosion resistance and long-term reliability. **Applications:** Ideal for fiber-to-the-desktop implementations, inter-switch connections, equipment room backbones, and long-distance building-to-building links. Perfect for organizations requiring extended reach without signal amplification. **Ordering Options:** Available in custom lengths beyond standard 70m configuration. Backed by a comprehensive 90-day limited warranty. Ships free from multiple US locations on orders exceeding $99. **Performance Specifications:** Attenuation: 1310nm at 0.25dB/km or 1550nm at 0.35dB/km. Tested for reliability in temperature ranges and outdoor-rated conditions when properly installed.
